Hosta plant named ‘Clovelly’

ABSTRACT

A new and distinct cultivar of ornamental  Hosta  plant named ‘Clovelly’ with heavily sinuate green leaves, deeply impressed veins, light lavender flowers well above foliage and matching bracts, suitable as a potted plant, for the garden, and for cut flower arrangements.

Botanical classification: Hosta hybrid (Tratt.)

Variety denomination: ‘Clovelly’.

BACKGROUND AND ORIGIN OF THE PLANT

The present invention relates to the new and distinct hosta plant, Hosta ‘Clovelly’ discovered by Kent A. Terpening in North Syracuse, N.Y. as the result of a self crossing of Hosta ‘Split Decision’ (not patented). The plant has been successfully asexually propagated by tissue culture methods at a nursery in Zeeland, Mich. and found to be stable and produce identical plants that maintain the unique characteristics of the original plant.

SUMMARY OF THE PLANT

Hosta ‘Clovelly’ differs from its parent, ‘Split Decision’, as well as all other hostas known to the applicant. The most similar known hosta cultivars: ‘Niagara Falls’ (not patented), ‘Candy Dish’ (not patented) and ‘Split Decision’ (not patented) are all green cultivars with sinuate margins. ‘Niagara Falls’ has a cascading habit and is larger in both habit and leaf size. ‘Split Decision’ has more drawn out and pointed leaf apex with a smaller ratio of leaf width to leaf length. ‘Candy Dish’ has shiny upper and lower leaf surfaces and is smaller in habit and leaf size and larger ratio of width to length. ‘Clovelly’ has a matte upper surface texture, a slightly shiny lower leaf surface, and the leaves are more horizontal than ‘Niagara Falls’. Hosta ‘Clovelly’ has a longer drawn-out leaf apex (more sharply pointed) than ‘Candy Dish’ and ‘Niagara Falls’, but less pointed than ‘Split Decision’. Hosta ‘Clovelly’ has a sinuate margin similar to ‘American Icon’ U.S. Plant Pat. No. 17,441, but the new plant is smaller and is solid green.

There are over 3,600 cultivars registered with The American Hosta Society, which is the International Cultivar Registration Authority for the genus Hosta. Hosta ‘Clovelly’ differs from these and all unregistered cultivars known to the inventor in that it has:

-   -   1. Rich green foliage with deeply undulated margins creating a         sinuate edge;     -   2. Compact habit, medium-sized clumps;     -   3. Tightly clustered flowers on scapes above foliage high enough         for each medium lavender flower to be effectively displayed,         each flower subtended by a bract with light lavender center         accenting and closely matching the flower color.

BRIEF DESCRIPTION OF THE DRAWINGS

The photographs of the new plant demonstrate the overall appearance of the plant, including the unique traits. The colors are as accurate as reasonably possible with color reproductions. Ambient light spectrum, source and direction may cause the appearance of minor variation in color.

DETAILED BOTANICAL DESCRIPTION

The following descriptions and color references are based on the 2001 edition of The Royal Horticultural Society Colour Chart except where common dictionary terms are used. The new plant, Hosta ‘Clovelly’, has not been observed under all possible environments. The phenotype may vary slightly with different environmental conditions, such as temperature, light, fertility, moisture and maturity levels, but without any change in the genotype. The following observations and size descriptions are of a three-year old plant in a garden in Zeeland, Mich. under light artificial shade canopy with supplemental water and fertilizer.

-   Botanical classification: Hosta hybrid. -   Parentage: Hosta ‘Split Decision’ (not patented) times ‘Split     Decision’. -   Propagation method: By sterile laboratory tissue culture division     and garden division.     -   -   Time to initiate roots from tissue culture.—About three             weeks. -   Rooting habit: Normal, fleshy, lightly branching. -   Plant description:     -   -   Plant shape and habit.—Hardy herbaceous mound forming             perennial with basal rosette leaves, usually bilateral and             radially symmetrical, spreading by rhizomes.         -   Crop time.—Summer growing 10 to 15 weeks to finish in a             one-liter container; vigor is good.         -   Plant size.—Foliage height at flowering is about 38 cm tall             from soil line to the top of the leaves and about 80 cm wide             at soil line. -   Foliage description:     -   -   Leaf blade.—Cordate leaf base with acute apex, 12 to 15 cm             long, 7 to 8 cm wide, average 14 cm long by 7 cm wide;             symmetrical; entire margin with sinuate undulations of about             1.5 cm; 9 to 11 pairs of major parallel deeply impressed             veins; top surface begins season slightly glaucous becoming             dull matte surfaced, and bottom surface is slightly shiny.         -   Blade color.—Adaxial (top) between RHS 137A and RHS 137B;             abaxial (underside): closest to RHS 138A. The 9 to 11 vein             pairs on either side of midrib are the color is the same as             the surrounding leaf tissue on both the top and bottom of             the leaf; midrib on abaxial side is lighter than RHS 138D             toward base of leaf becoming RHS 138A toward apex; midrib on             adaxial side is RHS 144A in the one third closest to the             base developing to RHS 137 A in the one third nearest the             apex.

The plant grows best with plenty of moisture and     adequate drainage, but is able to tolerate some flooding and drought     when mature. Hardiness at least from USDA zone 3 through 9, and     other disease resistance is typical of that of other hostas.
